To oil! whom it may concern.-

Be it known that i, Geenen F. A'rwoon, a citizen of the UnitedStates, residing at New York, in the county of NewYork and State of New York, have invented a certain new and usefui Im rovement in Windingldachines, of whic the follow-ing is a full, clear, concise, and exact description.

M invention relates to a Winding-machine, and -as for its object to provide-an improved mechanism for Winding wire upon f closed cores.

The machine is particuia'rly designed for winding loading-coils for telephonefcix cuits. Such coils consist of a ring-shaped core or' laminated iron having two Wire helice's wound upon semioircular segments thereof.

Mv principal object has been to produce a machine which will apply the wire radialiy to coils of this character where the coils are small and have a restricted opening in the center.

i will describe my invention by reference, to the eccompanying'drawinge, which illus,l trate a winding-machine embodying my ser# eral improvements, and the parte or combination" which .l considernovel will be pointed out in theappended claims. y

.Figure l is a view oi said windingmiachine in elevation, the ring-core upon which the wire is to be wound being shown in section. Fig. Zie a lan view of themachine. Fig. 3 is a ifertica sectional elevation. Figs. 4 and 5 are detail views oi' a drag mechanism for the rotating spool. Fig. 6 is a detail view showing how a segment of the winding-ring ma r be removed to permit the ring-core to be interlinked therewith. Fig. 7 is a detail view oi" the removable segment of the spool. Fig. 8 is a detail view of a bridge-piece which is fitted over the Winding-ringr to support and guide the wire from the spool to the sheave on the winding-ring. Fig. Q is a detail view ofthe holder for the ring-coil. Fig. l() is a detail vieu' in elevation, partially in seotion, showing the manner in which the Wire is-ied from the spool over the sheave or guide tothe core: and Fig. 11 is a detail end elevation, partially in section, oi the parte shown in Fig, 10.

The same letters of reference yare used to designate the same parts where`"er they are shown.

said rings The principal operating parte of the machine are the' spool-ring a. and winding-ring t, which are mounted side by side so as to rotate inde` endently of each other, both of sing 'provided with removable segments, sothat the closedcore may be interlinked therewith, and the winding-ring carrying a winding sheave or guide substantiaily in the cent-rai plane between the two rings. The wire to be wound upon the core is led from the s ool over the winding-sheave and thence to t e core. The Winding-ring b is adapted to be drivento carry the Wmdingsheeve around and through the core, and 1n its rotation the Wire is pulled ol the spool and wrapped around the core.

.in the machine shown the rings a' l1 are su ported upon two inde endent sets of whee s a. o', respectively, an the wheels b are ar-A ranged to be driven by s rocket-and-chain mechanism as shoWh, so' t at as said wheeis are rotated the winding-ring b is -frictionally driven. Thewheels are preferably grooved te iit 'corresponding inner beveled edges of the rings. ille set of wheels a is supported u on a suitable framework a3, while the set of w eels bis supported u on a similar framework b on the other si e, 'the two supports being independent, so that the space in the plane between the two vrings is left unobstructed to permit the passage of the wire therethrough. as it is being wound. A drag is provided for the spool-rin as shown in detnii in Fi s. 4 and 5. is drag' may be simply a b ook of iiber c, mounted to slide in guideways c c upon the framework ofthe machine, said drag being pressed against thev inner rim of the spool-rin a by means of a s ring d, acting through a. ever d', as shown. ne end of the spring may be hooked upon the lever which. engages the slidin drag, while the other end may be fastene to an adjustable anchor-d2. The spool-ring a `is provided with. a removable segment or gate o3, so that when said gate is removed the core e to be wound may be interlinked with said ring o. segmental opening for the same purpose, the two ends of said guide-ring being normall held vtogether by the removable turnbuckle Said turnbuokle forms, in effect, a removable segment of said winding-ring.

When the core is to be inserted, the turnbuckle ha' and the gate a3 are removed, and

IOO

Similarly the Winding-ring b has a core is in position they are replaced s tnrnbuclrle tightened tocontract the windiugcfing and bring the saine into iii-m engagement with the Jriction dri'VingWh-.eels t la', upon which. it is supported. All the wirst-hat is to be wound upon a given segment of the core must be first wound or spooled up upon. the spool-ringo after the core has been' interlinked therewith. Their the other end of the wire on the spool is led over a guiding sleave or pulley f, carried'by he r riding-ring to the core and fastened to ser. Upon the rotation of the windii g :f the wnding-sheave f is carried through and around the cor 'so that the aire is pulled o'ii the spool and wrapped ascend the core.

The windingsheave is preferably mounted in the side of the winding-ring next the s oolring, so that said shea-ve is substantial y in the central plane between tlc two rings. removable bridge gin the 'form of a segmental. plate'is attached to tle'periphe of the windingri1ig and extends rearward y for a short distance, spanning laterally the gap or space between tlc two rings. aid bridgepiece 'is preferably provided with guides or eyelets through which the wire is passed from the spool over said bridge on its way to the winding-sheave Preferably' only the set of wheels b b is positively driven, the' wheels a a being simply supports u lon which. tlfe spool-ring maj turn, ln ort er to drive the spool-ring while the wire is being spooled up on tle same, however, thc-two rings may be coupled to rotate together by means of a pin apassing through tl: em.

in the operation of thevmachmethe segnient e3 and the turnbuclzle b3 are first re 'moved and leave an opening through which 'the closed core e may be interlinkedrwith the' rings. The segment c3 and turnbuclle b3 are then replaced and locked in position and the two rings coupled together by means ofthe pin h. The machine is now ready to'spool up, and this operation is shown in Fig. 2, the driving mechanism being started to rotate the rings o; b in the direction opposite to that in which they will turn when the wire is being nnwound` from the s ool lto the core. ln s ooli'ng up the end opthe wire may be simp y fastened tothe spool in any convenient Way, the spoolset to rotating, and the wire guided onto the same by the hand of the o crater. During the spooling operation t ie drag may he taken off the spool by manipulating an adjusting-screw d3, acting upon a lever d. When a sufficient quantity of wire is wound upon the spool, the bridge-piece or peripheral plate g is attached to the windingring, said plate extending rearwardly a short distance from the guiding-sheave- The other end of the Wire is then passed through eyelets on the bridge-plate g, then passed over the seneca winding-sheavef, and from thence led to the core, passing through the unobstructed space between the two mountings of the rings a b. The end of the wire being fastened to the core, the driving mechanism is now started to rotate the winding-rin in the direction shown by the arrows in Figs. l and l0, It will be seen that as thering rotates the guidingsheave will. be carried around and throughv the core and the wire will be wraplped around said vcore.-

T e core is held horizontally in a standard k, which is pivoted at 7c to the bed-plate of Vthe machine in such a way that the core may be rotated about a vertical axis coinciding with the axis oi the core while the winding machine is in operation to guide the wire which is being applied to said core back and forth' through a semicircumference. The standard k may be rotated by means of a gear-train actuated by a ratchet-pawl m, carried u on an oscillating hand-lever l. The lever is pivoted to be oscillated t'o and fro between nx'ed'posts o o, and in its oscillation the ratchet-pawl m will advance the geartrain and rotate the core. When one half oi the core has been wound, it may be taken out of the holdingclamps 7c and turned around, whereupon the other half may be wound in the same, manner. -7.

Owing to the quantity of wire the spool has to carry to wind anordinary loading-coil, room can only be obtained by making the spool or'a large diameter. This necessitates a construction in which the body of the ring or coil being wound is quite eccentric to the winding-ring and spool. With a spool ,and winding-ring of large diameter, however, the wire is pulled 'od 'the spool during oneha'lf of a revolutiomwhile the guide-sheave is-moving away from the coil at a rate much faster than during the other half of the revolution, while the guiding-sheave is moving towardV the coil. This tends to the formation of slack wire, and the brakin .mechanism or IOO Lio

drag is applied to the v'spool` to prevent the spool from Arotating any faster than is re,-

quired by the amount of wire to be pulled OY 4 by the movement of the guide sheavc through a given arc. l

' A special advantage results from mountin the guidesheave substantially in the centra plane between the two rings, for the reason4 that the wirc may be wound radially upon the core without havin any great amount of space in the restricts o ening of the coil taken u chine. IInn other words, a coil may be wound in which thel inner di meter of the completed coil will be but slighty greater than the comn by the rings o the winding-mw' bined width of the spool-ring and guide-ring.

As shown, the cross-sectional area of the winding-ring and spool-ring together is reduced to a minimum by rounding the sides thereof. Theinside of the. spool-ring is also senses shown, to conform to'lthe eo that the maximum quenhollowed ou" curved out tity'of wire een be held therein without in-k creasing the specie which the ring wlll telre up in theinside oi thee-oil being wound.
